The type of camera you have could make the difference. As already noted do you have a setting called Macro? What brand and model is your camera? If your camera does not have a Macro setting, you still have other options. You could just get a magnifying glass stand and take the pictures though that. If your camera has threads on the outer part of the lens for filters, you may want to check a camera store for close up lens filters. Vivatar makes a great 3 filter enlargement set in numerous filter ring sizes. If your local photo store dose not carry that inticate types of camera impliments, try B&H company. That would be
www.bhphotovideo.com and request a catalog. There are many on line photo organizations but B&H is probably the largest in the world. If your camera dose have a threaded filter ring, it should have a notation somewhere on the front indicating the mm size which is important in purchasing filter size enlarging lenses. If you can not find then in your size, there are also adaptor rings available to change from one size to another. As to lighting, you could get silly there also and buy all kinds of lighting props from the same types of companies or just take the photos outside. During the daytime, that is. You may find that just putting a coin on a black bar-b-que grill will give the proper background. If the background is to light it may fool your cameras photo eye into thinking it has to shut down to much. Then also as already noted a tripod is most usefull. If you don't have one and don't wan't to buy one, try holding the camera a little more loosely. Take a deep breath and hold it while taking photos. If you hold a camera to tightly, you muscles being tightened cause you hands to shake ever so slightly. The reason to hold your breath is that while breathing, you chest expands and contracts, taking your arms with it and this also is a cause for poor quality photos.
